The science behind our products

When your patio, pathway, drive or terrace was first laid, the stone
would have looked beautiful. Over time, microscopic lichen spores carried by wind and rain from surrounding trees, land on the stone. If left untreated, lay down a root that feeds off the minerals within the stone. Eventually, the entire surface gets covered in what we call ‘Black Spots’ which no amount of pressure washing will fully remove!

Patio Black Spot Remover removes lichen, algae and instantly restores the natural colour to patios, paths, and garden stonework just as they were when new, no matter how old the stone, at a fraction of the original cost to lay.

Patio Black Spot Preventer applied annually, maintains the spotless finish, and removes algae within a few days, without the need to pressure wash.

Acid-based cleaners and endless pressure washing will permanently damage your stone. This approach will cause short and long term damage to plants in the surrounding area.

Sandstone is sedimentary; it cures in layers and splits in layers. The vibration caused by pressure washing causes these layers to delaminate, resulting in destroying the surface and breaking the stone.

Our products are biodegradable and acid free. Our expertise in stone led us to develop this unique system and it’s why top garden centres throughout the UK have chosen to stock our pioneering brand.
